Annisa wrote an expression that represents
“the product of 6.2 and the sum of 3c and 8.”
What are the factors of the expression?
Answer:
“the product of 6.2 and the sum of 3c and 8'' will be algebraically represented as:
⇒ (6.2) (3c + 8)
We know that the numbers that we multiply are the factors of the product.
Here, (6.2) and (3c+8) are the factors of the expression.
Step-by-step explanation:
Let us breakdown and translate the word expression into an algebraic expression.
The sum of 3c and 8 is algebraically represented as:
⇒ 3c + 8
Thus, “the product of 6.2 and the sum of 3c and 8'' will be algebraically represented as:
⇒ (6.2) (3c + 8)
We know that the numbers that we multiply are the factors of the product.
Here, (6.2) and (3c+8) are the factors of the expression.

Max has $17 in a fund he is creating to save for a bike. He adds $6 per week of his babysitting
earnings to the fund. If his weekly fund balance is represented by an arithmetic sequence, find
the 27th term.
The 27th term is $173.
In an arithmetic progression the difference between the two consecutive terms is same.
Here it is given that the first term of the AP which is represented by a is $17.
And Max adds $6 after every week in his fund so the common difference d is $6.
We know the general expression to find the nth term of an AP is
= a+(n-1)d
Here we have to find the 27th term. so the value of n will be 27.
Now the 27th term of the AP = 17+(27-1)6
= 17+156
= $ 173
The balance in the fund after 27th week will be $173.

Suppose you borrow $680 for a term of three years at simple interest and 3.94% APR. Determine the total (principal plus interest) you must pay back on the loan.
The total amount that we need to pay back after the end of 3 years with principal amount as $ 680 and simple interest as 3.94 % will be $ 760.376.
We are given that:
Principal amount = P = $ 680
Time period = t = 3 years
Simple interest rate = r = 3.94 %
We know that, the formula for simple interest is given by:
SI = P × r × t
SI = 680 × 3.94 % × 3
SI = 80.376
Amount will become:
Amount = $ 680 + $ 80.376
Amount = $ 760.376
Therefore, we get that, the total amount that we need to pay back after the end of 3 years with principal amount as $ 680 and simple interest as 3.94 % will be $ 760.376.

Answer:
87, if it were 45 degrees, it would be 90, closest to 90 is 87
Answer:
87 feet
Step-by-step explanation:
We have an angle that's 44 degrees and we know that Susan is 90 feet from the base of the tree. We need to know the height of the tree, which is the value opposite from the angle we know.
Use tangent to find height.
tan (44) = x / 90 then multiply both sides by 90
x = tan (44) * 90 evaluate tan(44) and substitute into the equation
x = 86.911

Determine the cubic function obtained from the parent function y=x^3 after each sequence of transformations.
a reflection across the x-axis; a translation 1 unit up; and a translation 2 units right
Answer:
-(y+3)=(x-2)^3
Step-by-step explanation:
Transformed function B is f' ( x ) = - ( x - 2 )³ + 1
The transformed function is given by y = - ( x - 2 )³ + 1
How does the transformation of a function happen?
The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the parent function be denoted as A
Now , the value of A is
y = x³
Let the transformed function be denoted as B
Now , the value of B is calculated by
Step 1 :
A reflection across the x-axis
So , the function changes to g ( x ) = -x³
Step 2 :
A translation 1 unit up
Up by d units: y = f(x) + d
So , the function changes to h ( x ) = -x³ + 1
Step 3 :
A translation of 2 units right
Right shift by c units: y=f(x-c)
So , the function changes to f' ( x ) = - ( x - 2 )³ + 1
Therefore , the value of B is f' ( x ) = - ( x - 2 )³ + 1
Hence , the transformed function B is f' ( x ) = - ( x - 2 )³ + 1

An 80-foot diameter reservoir currently holds 825,000 gallons of water. What is the depth of water in this reservoir, measured in feet?
Answer:
Step-by-step explanation:
d=80 ft
r=80/2=40 ft
volume of cylinder=π r²h,where h is height or depth of cylinder.
π×40²×h=825,000
πh=825,000/40²=4125/8
h=4125/(8π)≈164.1285≈164.13 ft
The depth of water in the reservoir is approximately 21.92 feet.
To find the depth of water in the reservoir, we can use the formula for the volume of a cylinder:
Volume = π * r^2 * h
Where:
Volume is the total volume of water in the reservoir (in gallons),
π (pi) is a mathematical constant approximately equal to 3.14159,
r is the radius of the reservoir (half of the diameter), and
h is the depth of water in the reservoir (in feet).
Given:
Diameter = 80 feet
Volume = 825,000 gallons
We first need to calculate the radius (r) of the reservoir:
Radius (r) = Diameter / 2 = 80 feet / 2 = 40 feet
Now, we can convert the volume from gallons to cubic feet because we need the measurements to b²e in consistent units:
1 gallon ≈ 0.13368 cubic feet
Volume (in cubic feet) = 825,000 gallons * 0.13368 cubic feet/gallon ≈ 110,127 cubic feet
Now, we can find the depth (h) using the formula:
110,127 cubic feet = π * (40 feet)² * h
Solving for h:
h = 110,127 cubic feet / (π * 40 feet)² ≈ 110,127 cubic feet / 5026.5482 square feet ≈ 21.92 feet
Therefore, the depth of water in the reservoir is approximately 21.92 feet.

A 16 oz bottle of a new soda costs $3.59. What is the unit rate, rounded to the nearest tenth of a cent?
The unit rate is __ cents per oz.
The unit rate is 22.5 cents per oz .
The unit rate of any quantity is calculated by dividing (total cost) with (total units purchased).
For Example : If 12 bananas cost $120 then 1 banana will cost 120/12=$10.
In the given question
16oz bottle costs $3.59.
As we have to find the unit rate in cents per oz , we first convert $3.59 to cents.
We know that
$1=100cents
$3.59=100*3.59
=359cents
So the price of 16 oz bottle = 359 cents
Unit rate = (total price ) / (units purchased)
Substituting the total price as 359 cents and units purchased as 16oz.
Unit rate = 359/16
=22.4375
≅22.5
Therefore , the unit rate is 22.5 cents per oz.
